Habitat and spatial trends of U.K. wintering waterbird populations over 50 years. [PDF]
Conserv BiolAbstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Effects of nitrogen deposition on territory numbers of breeding birds. [PDF]
Conserv BiolAbstract Deposition of atmospheric N (nitrogen) is assumed to be a major cause of biodiversity decline in Europe. To date, few studies on the direct or indirect effects of N on bird species have been conducted. Using Swiss bird count data and habitat data, we analyzed the correlation of N deposition with numbers of territories of 112 breeding bird ...

Global review of shorebird tracking data to identify research gaps and conservation priorities. [PDF]
Conserv BiolAbstract Tracking has enabled rapid advances in knowledge of the movement behavior and habitat use of shorebirds and is thus making a growing contribution to their conservation. However, realizing the full potential that tracking holds for conservation involves understanding what has been performed on shorebirds to date and identifying regional and ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States. [PDF]
Conserv BiolAbstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

Wintering Together: Do Migrants Impact Residents? A Literature Review. [PDF]
Ecol EvolThis review examines the overlooked impacts of interspecific competition on resident tropical birds during the overwintering period, highlighting the need for a deeper understanding of their interactions with migratory species. By evaluating the literature through the lens of competition theory, we identify critical gaps in knowledge and suggest that ...
